数词用法讲解及练习

数词用法讲解及练习

数词I.定义与分类数词是指表示数目多少或顺序先后的词。

表示数目多少的数词叫基数词,如one, five, ten, thirty, sixty-five 等;表示顺序先后的数词叫序数词,如first, sixth, tenth, twenty-first 等。

数词用法相当于名词和形容词,在句中可用作主语、宾语、表语、定语、同位语等。

II. 基数词1. 英语中没有“万”这个读数单位,要表示汉语中的“万”,英语需借用thousand一词,如“一万”用“十个千”表示(ten thousand),“十万”用“一百个千”表示(one hundred thousand)。

2. 用作基数词单位的hundred, thousand, million, billion 通常不带复数词尾-s,但若用于表示数百、数千、数百万这样的泛指,则用复数。

如:About two thousand people died in the earthquake. 大约有两千人在地震中丧生。

Thousands of people go to the seaside every year. 每年成千上万的人到海滨去。

3. 表示整十的基数词用复数形式可以表示人的大约岁数或年代。

如:He is in his early twenties. 他才二十出头(from 。

This took place in the 1930s. 这事发生在20世纪30年代。

III. 序数词1. 许多序数词是由相应的基数词后加词尾-th构成的,如four / fourth,six / sixth,ten / tenth,sixteen / sixteenth,但是nine变为序数词是ninth,而不是nineth。

2. twentieth, thirtieth, fortieth 等表示整十的序数词,由相应的基数词将词尾y改为ie,再加-th 构成。

3. first, second, third 通常可缩写为1st, 2nd, 3rd。

数词讲解一.数词分为基数词和序数词两种,基数词表数目,序数词表顺序。

基本构成(一)基数词——从1数到N1.1—12的基数词是独立的单词,即:one,two,three,four,five,six,seven,eight,nine,ten,eleven,twelve.2.13—19的基数词以-teen结尾。

如:fourteen,seventeen等,但13,15,18较特殊,13—thirteen 15—fifteen 18—eighteen.3.20—90的整十位均以-ty结尾。

如:sixty,ninety,但20,30,40,50,80较特殊,20—twenty,30—thirty,40—forty ,50—fifty ,80—eighty.4.十位数与个位数之间要加连字符号―-‖,如:28—twenty-eight,96—ninety-six.5.百位和十位(若无十位则和个位)之间加and,如:148—one hundred and forty-eight,406—four hundred and six.6.hundred(百),thousand(千),million(百万),billion(十亿)等前面即使有具体的数词,也不能在它们的后面加s.如:600—six hundred, 8百万—eight million.7.1000以上的数字,从后往前数每三位加一个逗号―,‖第一个逗号前为千(thousand),第二个逗号前为百万(million),第三个逗号前为billion(十亿)。

如:2,510=two thousand five hundred and ten;84,296=eighty-four thousand two hundred and ninety-six;274,350=two hundred and seventy-four thousand three hundred and fifty.8.hundred,thousand,million用复数形式修饰名词时要用―of+复数名词‖,如:数以百计的年轻人hundreds of young people;数以千计的书thousands of books.注意:hundreds of/thousands of/millions of +复数名词,其前面不能加具体的数词,但可加several或many.Hundreds of new buildings have sprung up here this year.Thousands upon thousands of people in South Africa are rising against their oppressors.Thousands and thousands of people come to visit the city every day.(二)序数词——由基数词转变而来,表示―这是第N个‖1.口诀巧记基数词变序数词:―一、二、三,特殊记,八去‖t―,九去‖e―,‖ve―要用‖f―替,见‖y―变成‖i―和‖e―,词尾加上‖th―,若是遇到几十几,只变个位就可以。
